It wasn't at their booth. I looked. So, I cornered one of the reps and asked them about it. Mainly I wanted to know why they would spend so much $ on the project and abandon it (original designs, re-design, prototype, secure the rights to the BrenTen name, etc).
To my surprise he replied that it wasn't dead. In fact, he said that they had just released a blog post update about it. I couldn't find it. That was disappointing. Maybe it is buried somewhere, but the fact that they didn't even have the prototypes that they had from years ago wasn't encouraging.
He reiterated the previous blog posts that there were problems with the original castings. Fair enough, but we have been hearing this for a while. But, I remain hopeful. After all, he could just have said that the project was DOA and ended the conversation quickly.
